Special Issue Information

Dear Colleagues,

Microstructural characterization and property analysis of alloys involve a number of disciplines, including materials science, physics and chemistry, and aim to extensively explore the influence of the microstructure of alloys on their macroscopic properties. In this Special Issue, we will introduce the applications of alloy microstructural characterization and property analysis in aerospace, transportation, energy and environmental protection, biomedicine and other fields with practical cases to demonstrate their important roles in practical engineering and scientific research. At the same time, we will also focus on the cutting-edge developments in the field of microstructural characterization and property analysis of alloys, share the latest research results and technological advances, and provide readers with useful references. By reading this Special Issue, you will learn the basic concepts, methodological principles and application cases of microstructural characterization and property analysis of alloys, which will help you to improve your professionalism and research level in related fields. At the same time, this Special Issue will also provide a platform for you to communicate and share experiences with your peers, and jointly promote the development of the field of alloy microstructural characterization and property analysis.

In order to improve the wear resistance of copper and enhance the surface properties of copper parts, this article uses BN nanoparticles as a reinforcing phase and the laser remelting method to prepare a Cu/BN remelted layer on the copper surface. The surface morphology, crystal structure, microhardness, and wear resistance of the samples were tested and characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), a microhardness tester, and a friction and wear tester. The effects of laser frequency, pulse width, and energy density on the surface morphology and wear resistance of the samples were analyzed and studied, and the effects of the laser parameters on the properties of the Cu/BN remelted layer were discussed. The research results indicate that laser frequency, pulse width, and energy density have a direct impact on the surface morphology and properties of the Cu/BN remelted layer, but the impact mechanism by the above parameters on the remelted layer is different. The effects of laser frequency on the remelted layer are caused by changes in the overlap mode of the remelting points, while laser pulse width and energy density are achieved through changes in remelting intensity. When the laser frequency is 10 Hz, the pulse width is 10 ms, and the energy density is 165.8 J/mm2, the Cu/BN remelted layer has better surface properties. Full article
